without touching it? no what you will have to do is sand or scrape the pipe then you will be able to tell the difference. if its a dull metal then its black iron but if it shines then it would be galvanized.

Galvanized Sheet Metal
Yes.
Even though I am in a different country, you should use Black Iron pipe, not galvanized. The other option is copper. Check your local bylaws, GET A PERMIT! This is essential. If you screw up and do not have a permit, you will NOT be covered by insurance!
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
Yes, first the Galvanized pipe has to be threaded with a standard thread for pipes, then you buy the correct female socket threaded plastic fitting, screw it onto the pipe using Thread pipe sealing tape, then glue your piping into the socket part of the plastic fitting, simple. Cheers.
